Impact

I. AESTHETICS – Would the project:

a. Have a substantial adverse effect on a scenic vista? No designated scenic vistas exist in the vicinity of the project routes.

b. Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway?

The project routes do not cross or travel within any designated scenic highway. c. Substantially degrade the existing visual character

or quality of the site and its surroundings?

Conduit and cable installation will have a temporary visual impact during construction. d. Create a new source of substantial light or glare,

which would adversely affect day or nighttime views in the area?

The conduit and cable will be buried underground and will not be a source of any light or glare. Construction is anticipated to occur during daylight hours; some nighttime work may be required to accommodate traffic flows. II. AGRICULTURE RESOURCES – In determining whether impacts to agricultural resources are significant

environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the California Dept. of Conservation as an optional model to use in assessing impacts on agriculture and farmland. Would the project:

a. Convert Prime Farmland, Unique Farmland, or

Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use?

There are no agricultural uses or OP-AMP stations proposed along the project routes. No impact will occur on agricultural resources since construction will occur in existing disturbed rights-of-way that are not currently in agricultural production. b. Conflict with existing zoning for agricultural use, or a

Williamson Act contract?

Construction will occur in existing road rights-of-way and will not have an impact on Williamson Act land by requiring or resulting in its conversion to nonagricultural uses. C Involve other changes in the existing environment,

which, due to their location or nature, could result in conversion of Farmland, to non-agricultural use?

The project will create no demand on agricultural land and exert no pressure for conversion to another use.

III. AIR QUALITY – Where available, the significance criteria established by the applicable air quality management or air pollution control district may be relied upon to make the following determinations. Would the project:

a. Conflict with or obstruct implementation of the

applicable air quality plan?

The construction, maintenance, and operation of the project will not require the use of equipment or materials that would conflict with or obstruct with implementation of the applicable air quality plans for the project areas. b. Violate any air quality standard or contribute

substantially to an existing or projected air quality violation?

Heavy equipment will produce temporarily increased levels of air pollutants during construction, which may lead to violations of air quality standards. Implementation of construction best management practices (BMPs) will assure that any potential air quality impacts are less than significant.

Impact

No

Impact

c. Result in a cumulatively considerable net increase

of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)?

The project is not expected to exceed air quality standards and construction is temporary in nature, therefore a cumulative considerable net increase for any non-attainment criteria pollutant will not occur. d. Expose sensitive receptors to substantial pollutant

concentrations?

Heavy equipment will produce temporarily increased levels of air pollutants during construction, which may potentially expose sensitive receptors to elevated levels of exposure. Implementation of construction best management practices (BMPs) will assure that any potential air quality impacts are less than significant. e. Create objectionable odors affecting a substantial

number of people?

Construction will temporarily generate odors from diesel exhaust, but will not be severe or affect a substantial number of people.

IV. BIOLOGICAL RESOURCES – Would the project: a. Have a substantial adverse effect, either directly or

through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service?

Construction activities could result in impacts to nesting raptors, including Swainson’s hawk and burrowing owl, and to the valley elderberry longhorn beetle. Mitigation measures include pre-construction surveys to identify raptor nests and suitable valley elderberry longhorn beetle habitat and, if these features are located, requirements for avoidance during critical periods. b. Have a substantial adverse effect on any riparian

habitat or other sensitive natural community identified in local or regional plans, policies, regulations, or by the California Department of Fish and Game or US Fish and Wildlife Service?

Project routes do not cross any creeks, streams, or other water features and construction would not impact sensitive vegetative communities. c. Have a substantial adverse effect on federally

protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means?

Project routes do not cross any creeks, streams, or other water features, including vernal pools, wetlands, or riparian habitat. d. Interfere substantially with the movement of any

native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites?

Temporary construction within existing rights-of-way would not interfere with migration or impede wildlife dispersal. e. Conflict with any local policies or ordinances

protecting biological resources, such as a tree preservation policy or ordinance?

Heritage trees may be present along the routes, but the applicant would avoid these resources to the maximum extent practical or work with local jurisdictions to minimize impacts to these resources. f. Conflict with the provisions of an adopted Habitat

Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan?

The proposed project would not conflict with existing HCPs or conservation plans.

V. CULTURAL RESOURCES – Would the project: a. Cause a substantial adverse change in the

significance of a historical resource as defined in §15064.5?

b. Cause a substantial adverse change in the

significance of an archaeological resource pursuant to §15064.5?

Ground disturbing activities could inadvertently affect cultural resources and the completed literature review yielded both historic and/or prehistoric sites along several of the routes, as well as the potential for sacred lands. Implementation of mitigation measures such as avoidance procedures and construction monitoring will reduce impacts to less than significant levels. c. Directly or indirectly destroy a unique

paleontological resource or site or unique geologic feature?

Ground disturbing activities could inadvertently affect paleontological resources and the completed literature review identified high sensitivity for paleontological resources along several of the routes. Paleontological monitors will be employed in high sensitivity areas to recover, analyze, process, catalog, curate, and document fossil remains. In the event of a significant fossil discovery, construction will cease and salvage operations implemented. d. Disturb any human remains, including those interred

outside of formal cemeteries?

During construction activities, it is possible that human remains might be encountered. Compliance with state laws will ensure that potential impacts to human remains are below less than significant levels.

VI. GEOLOGY AND SOILS – Would the project: a. Expose people or structures to potential substantial

adverse effects, including the risk of loss, injury, or death involving:

i. Rupture of a known earthquake fault, as delineated

on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42.

ii. Strong seismic ground shaking? iii. Seismic-related ground failure, including

liquefaction?

iv. Landslides? The cable system will be designed to allow the cable to accommodate earthquake fault offsets at the soil surface. Damage to the system will not have an adverse affect on humans or the environment. b. Result in substantial soil erosion or the loss of

topsoil?

The potential exists for erosion of fill and excavated material during construction, although construction will take place in paved rights-of-way. Appropriate erosion control measures including implementation of best management practices (BMPs) will be employed to reduce erosion to less than significant levels. c. Be located on a geologic unit or soil that is unstable,

or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction or collapse?

Damage to the system will not have an adverse physical effect on humans or the environment. d. Be located on expansive soil, as defined in Table

18-1-B of the Uniform Building Code (1994), creating substantial risks to life or property?

Proper engineering and construction techniques will eliminate this hazard. Damage to the system will not have an adverse physical effect on humans or the environment

e. Have soils incapable of adequately supporting the

use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater?

No septic tank or alternative waste disposal system will be installed. No impacts will occur to any soils ability to support septic tanks or alternative wastewater treatment facilities.

VII. HAZARDS AND HAZARDOUS MATERIALS – Would the project: a. Create a significant hazard to the public or the

environment through the routine transport, use, or disposal of hazardous materials?

b. Create a significant hazard to the public or the

environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment?

Small quantities of hazardous materials will be stored, used, and handled during construction and may be released in accidental spills. Subsurface hazardous materials may be encountered during construction. Mitigation measures, which include best management practices, compliance with state OSHA requirements, and construction worker training will reduce effects to less than significant levels. c. Emit hazardous emissions or handle hazardous or

acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school?

No hazardous emissions will be generated by the project. No hazardous emissions or acutely hazardous materials, substances, or waste will be handled within one-quarter mile of an existing or proposed school d. Be located on a site which is included on a list of

hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment?

All listed hazardous materials sites will be identified prior to construction and avoided through reroutes. e. For a project located within an airport land use plan

or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area?

f. For a project within the vicinity of a private airstrip,

would the project result in a safety hazard for people residing or working in the project area?

There will be no structures that will impair airport operations or endanger people residing in the area or other land uses. g. Impair implementation of or physically interfere with

an adopted emergency response plan or emergency evacuation plan?

Emergency access will be regulated as a condition of the road encroachment permits by the applicable regulatory agency. h. Expose people or structures to a significant risk of

loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands?

The project will not expose people or structures to a significant risk of loss, injury, or death due to wildland fires since the routes are located within highly urbanized areas.

VIII. HYDROLOGY AND WATER QUALITY – Would the project: a. Violate any water quality standards or waste

discharge requirements?

Water quality could be affected by accelerated erosion or sedimentation or releases of petroleum hydrocarbons. Implementation of best management practices will reduce potential impacts to less than significant levels.

b. Substantially deplete groundwater supplies or

interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (e.g., the production rate of pre-existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)?

Installation of the conduit and cable will not typically exceed four feet and will have no impact on groundwater supplies or interfere with groundwater recharge. c. Substantially alter the existing drainage pattern of

the site or area, including through the alteration of the course of a stream or river, in a manner which would result in substantial erosion or siltation on or off-site?

d. Substantially alter the existing drainage pattern of

the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off-site?

No modifications to existing drainage patterns are anticipated as a result of the project. e. Create or contribute runoff water which would

exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff?

f. Otherwise substantially degrade water quality? The project will not create or contribute runoff water to drainage systems. g. Place housing within a 100-year flood hazard area

as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map?

No housing is proposed as part of the project. h. Place within a 100-year flood hazard area structures

which would impede or redirect flood flows?

Conduit and cable installation underground will not affect floodplain capacity and will not impede or redirect flood flows. i. Expose people or structures to a significant risk of

loss, injury or death involving flooding, including flooding as a result of the failure of a levee or dam?

The project will not affect any surface water flows nor increase the risk of flooding. j. Inundation by seiche, tsunami, or mudflow? The project will not affect the potential for inundation by seiche, tsunami, or mudflow.

IX. LAND USE AND PLANNING – Would the project: a. Physically divide an established community? Installation of the conduit and cable components will occur underground within existing road rights-of-way. Installation, operation, and maintenance will not create any structures or other features large or intrusive enough to physically divide any community. b. Conflict with any applicable land use plan, policy, or

regulation of an agency with jurisdiction over the project (including, but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect?

The project is not anticipated to conflict with local land use plans and regulations. If required, all necessary local zoning permits will be acquired prior to construction.

Impact

No

Impact

c. Conflict with any applicable habitat conservation

plan or natural community conservation plan?

Construction within existing rights-of-way will not conflict with local habitat and natural community conservation plans.

X. MINERAL RESOURCES – Would the project: a. Result in the loss of availability of a known mineral

resource that would be of value to the region and the residents of the state?

b. Result in the loss of availability of a locally important

mineral resource recovery site delineated on a local general plan, specific plan or other land use plan?

The routes are located within existing road rights-of-way, which limits the availability for surface mining and will not obstruct the recovery of mineral deposits to any greater extent than currently exists.

XI. NOISE – Would the project result in: a. Exposure of persons to or generation of noise levels

in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies?

b. Exposure of persons to or generation of excessive

groundborne vibration or groundborne noise levels?

Construction of the project will temporarily increase noise levels and groundborne vibrations in the project areas. This temporary construction-related increase will not exceed noise ordinances or other standards applicable in the project areas. Mitigation measures will reduce potential noise increases to less than significant levels. c. A substantial permanent increase in ambient noise

levels in the project vicinity above levels existing without the project?

Permanent noise increases will not result from implementation of the project. d. A substantial temporary or periodic increase in

ambient noise levels in the project vicinity above levels existing without the project?

Construction of the project will result in only temporary increases in noise levels. Mitigation measures will reduce potential noise increases to less than significant levels. e. For a project located within an airport land use plan

or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels?

Not applicable to the project. f. For a project within the vicinity of a private airstrip,

would the project expose people residing or working in the project area to excessive noise levels?

Not applicable to the project.

XII. POPULATION AND HOUSING – Would the project: a. Induce substantial population growth in an area,

either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)?

The purposed of the project is to increase the availability of telecommunication services in the project areas. The project will not directly or indirectly induce population growth. b. Displace substantial numbers of existing housing,

necessitating the construction of replacement housing elsewhere?

c. Displace substantial numbers of people,


Construction will occur within existing road rights-of-way and there will be no impact on population or housing.

XIII. PUBLIC SERVICES – Would the project: a. Result in substantial adverse physical impacts

associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the public services:

Fire protection? Police protection? Schools? Parks? Other public facilities?

Since the project will not result in any employment or population growth, it will not create a new demand for governmental services or facilities and will not require construction, alteration, or expansion of any such facilities to provide acceptable levels of service.

XIV. RECREATION – Would the project: a. Increase the use of existing neighborhood and

regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated?

b. Does the project include recreational facilities or

require the construction or expansion of recreational facilities, which might have an adverse physical effect on the environment?

The project will not result in increase us of recreation facilities or include the construction or expansion of recreational facilities.

XV. TRANSPORTATION/TRAFFIC – Would the project: a. Cause an increase in traffic, which is substantial in

relation to the existing traffic load and capacity of the street system (i.e., result in a substantial increase in either the number of vehicle trips, the volume to capacity ratio on roads, or congestion at intersections)?

The project will result in minor increases in traffic during construction. Vehicles will be used for transport of materials and field crews. Conduit installation within paved roadways will temporarily disrupt existing transportation and circulation patterns in the vicinity. Traffic control measures such as preparation of a traffic control plan and compliance with road encroachment permits will reduce traffic congestion during construction. b. Exceed, either individually or cumulatively, a level of

service standard established by the county congestion management agency for designated roads or highways?

Construction-related traffic impacts will be short-term. The project will not generate enough traffic during peak hours to change the LOS on area roads. Mitigation will be implemented to ensure impacts are less than significant. c. Result in a change in air traffic patterns, including

either an increase in traffic levels or a change in location that results in substantial safety risks?

The project will not result in construction of any towers or other impediments to air traffic.

d. Substantially increase hazards due to a design

feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)?

The conduit and cable will be installed underground and the facilities are compatible with existing subsurface utilities. e. Result in inadequate emergency access? The project will result in temporary lane closures. Traffic control measures such as preparation of a traffic control plan and compliance with road encroachment permits will ensure priority passage by emergency vehicles. f. Result in inadequate parking capacity? Vehicle parking during construction will be limited to areas delineated in the encroachment permit issued by the appropriate governing agency. g. Conflict with adopted policies, plans, or programs

supporting alternative transportation (e.g., bus turnouts, bicycle racks)?

The project will have no lasting demand on alternative transportation or on alternative transportation facilities.

XVI. UTILITIES AND SERVICE SYSTEMS – Would the project: a. Exceed wastewater treatment requirements of the

applicable Regional Water Quality Control Board?

Best management practices for erosion and sedimentation control will meet the requirements for storm water quality by the applicable regional water quality control board. b. Require or result in the construction of new water or

wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects?

The project does not require water for operation or maintenance and will not result in population growth that may require the construction of new or wastewater facilities. Best management practices for erosion and sedimentation control will meet the requirements for storm water quality by the applicable regional water quality control board. c. Require or result in the construction of new storm

water drainage facilities or expansion of existing facilities, the construction of which could cause significant environmental effects?

The project will not require or result in the construction of storm water drainage facilities. d. Have sufficient water supplies available to serve the

project from existing entitlements and resources, or are new or expanded entitlements needed?

The project will require no external water supply, so sufficient water supplies exist without requiring new or expanded entitlements. e. Result in a determination by the wastewater

treatment provider which serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments?

The project will not affect wastewater treatment services, as no wastewater will be generated. f. Be served by a landfill with sufficient permitted

capacity to accommodate the project’s solid waste disposal needs?

Construction debris consisting of spools and other packaging material associated with the conduit and cable will not significantly reduce landfill capacity. g. Comply with federal, state, and local statutes and

regulations related to solid waste?

The project will produce minimal amounts of solid waste. The project will comply with federal, state, and local statues and regulations related to solid waste.

XVII. MANDATORY FINDINGS OF SIGNIFICANCE



Impact

Incorporation


Impact

No

Impact

a. Does the project have the potential to degrade the

quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory?

Potential impacts on cultural resources during construction will be reduced to less than significant with implementation of the proposed mitigation measures. No impacts on fish, wildlife, plants, and their habitats are anticipated. b. Does the project have impacts that are individually

limited, but cumulatively considerable? ("Cumulatively considerable" means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)?

The impacts of the project will be negligible or less than significant. Through compliance with standards established for environmental protection, and incorporation of project elements and mitigation measures designed to primarily avoid or reduce impacts below the level of significance, the project will not make a cumulatively considerable contribution to any significant cumulative impact. c. Does the project have environmental effects, which

will cause substantial adverse effects on human beings, either directly or indirectly?

Implementation of the proposed projects will not cause a substantial adverse effect either directly or indirectly on human beings in the project areas because potential noise impacts during construction will be reduced to less than significant with implementation of the proposed mitigation measures. In addition, construction activities will be temporary and highly localized.




PROJECT: Los Angeles to Ontario Longhaul Route

DATE: October 3, 2001



PROJECT DESCRIPTION: The project involves the construction and operation of an underground fiber optic telecommunication system between Los Angeles and Ontario, California. The proposed project would involve the placement of fiber optic conduit and cable within previously disturbed areas within existing railroad and public road rights-of-way. The route is approximately 45.6 miles long, the majority of which (42.3 miles) is within railroad right-of-way. The fiber optic facilities will be installed at an average depth of 42 inches primarily through the use of a rail plow or tractor plow, supplemented by trenching and directional boring where required. Street crossings, waterway crossings, rail facilities, and other utilities will be avoided using directional boring. ENVIRONMENTAL FACTORS POTENTIALLY AFFECTED: The environmental factors checked below would be potentially affected by this project, involving at least one impact that is a “Potentially Significant Impact” as indicated by the checklist on the following pages.

The affect of increased nighttime noise and ground vibration levels will be reduced to less than significant levels by the mitigation measures included as part of the project.




PROJECT: Ontario to San Diego Longhaul Route

DATE: August 20, 2001



PROJECT DESCRIPTION: The project involves the construction and operation of an underground fiber optic telecommunication system between Ontario and San Diego, California. The proposed project would involve the placement of fiber optic conduit and cable within previously disturbed areas within existing public road and utility corridor rights-of-way, and construction of two OP-AMP stations. The route is approximately 114 miles in length. The fiber optic facilities will be installed at an average depth of 42 inches primarily by trenching within paved rights-of-way, plowing in road shoulders, and directional boring where required. Street crossings, sensitive environmental resources, rail facilities, and other utilities will be avoided using directional boring. ENVIRONMENTAL FACTORS POTENTIALLY AFFECTED: The environmental factors checked below would be potentially affected by this project, involving at least one impact that is a “Potentially Significant Impact” as indicated by the checklist on the following pages.

I. AESTHETICS – Would the project: a. Have a substantial adverse effect on a scenic vista? No designated scenic vistas exist in the vicinity of the project route. b. Substantially damage scenic resources, including,

but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway?

The project route does not cross or travel within any designated scenic highway. c. Substantially degrade the existing visual character


Conduit and cable installation will have a temporary visual impact during construction. Trenching outside paved roadways could leave a landscape scar for a short time. Implementing erosion control measures such as replacing topsoil and reseeding disturbed areas will mitigate visual impacts along the cable route. The two OP-AMP stations are not located on sites supporting sensitive resources and their use is consistent with local general plans and surrounding land uses. Existing vegetation and distance to adjacent residential uses will provide buffering. . d. Create a new source of substantial light or glare,


The conduit and cable will be buried underground and will not be a source of any light or glare. Construction is anticipated to occur during daylight hours; some nighttime work may be required to accommodate traffic flows. The single security light and exterior door lights at the OP-AMP stations will be similar to a standard residential porch light. II. AGRICULTURE RESOURCES – In determining whether impacts to agricultural resources are

significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the California Dept. of Conservation as an optional model to use in assessing impacts on agriculture and farmland. Would the project:



Construction of the cable route will occur in existing road rights-of-way. There are no existing agricultural uses on either of the two proposed OP-AMP sites. One OP-AMP station is zoned for agricultural use, but will not require conversion of a significant amount of land from agricultural use (less than 3,000 square feet). b. Conflict with existing zoning for agricultural use, or a


The OP-AMP stations are considered a “compatible” use in agricultural preserves and are allowed on agricultural land that is subject to Williamson Act contract. Construction of the cable route will occur in existing road rights-of-way and will not have an impact on Williamson Act land by requiring or resulting in its conversion to nonagricultural uses. c. Involve other changes in the existing environment,


Construction activities could introduce noxious weeds to previously uninfested agricultural areas. Broadwing will avoid dispersal of noxious weeds by designating wash stations at appropriate locations and implementing mitigation measures to minimize the possibility of spreading noxious weeds to uninfested areas. III. AIR QUALITY – Where available, the significance criteria established by the applicable air quality

management or air pollution control district may be relied upon to make the following determinations. Would the project:



The construction, maintenance, and operation of the project will not require the use of equipment or materials that would conflict with or obstruct with implementation of the applicable air quality plans for the project area.

Heavy equipment will produce temporarily increased levels of air pollutants during construction, which may lead to violations of air quality standards. The diesel-powered engines running the emergency backup generators at the OP-AMP stations will emit air pollutants during the infrequent periods they are in use. Implementation of construction best management practices (BMPs) will assure that any potential air quality impacts are less than significant. c. Result in a cumulatively considerable net increase

Construction will temporarily generate odors from diesel exhaust, and the infrequent operation of the emergency back-up generators at the OP-AMP sites, but odors will not be severe or affect a substantial number of people. IV. BIOLOGICAL RESOURCES – Would the project: a. Have a substantial adverse effect, either directly or


The project could result in impacts to listed wildlife species, raptors, and listed fish species. The least Bell’s vireo, California gnatcatcher, southwestern willow flycatcher, raptors, and other listed bird species could be impacted by noise and increased human activity in the construction zone resulting in nest abandonment. The arroyo chub, Santa Ana sucker, arroyo toad, western spadefoot, southwestern pond turtle and other aquatic species could be directly and indirectly impacted by construction activities in and around rivers. Mitigation measures include conducting nesting period surveys for the least Bell’s vireo, California gnatcatcher, willow flycatcher, and raptors, and employing avoidance measures if nests are detected and construction activities would occur during the nesting season. Impacts to the sensitive species utilizing aquatic habitats would be avoided by using directional boring techniques and applying exclusion zones near riparian areas and rivers. Mitigation in the event of a frac-out is included. Construction activities could result in impacts to the Delhi sands flower-loving fly. Mitigation measures include pre-construction surveys to identify suitable habitat and, if located, requirements for avoidance during critical periods. b. Have a substantial adverse effect on any riparian


Some woody vegetation may be trimmed or removed in reaches of the project route, which parallel riparian habitat or support large, native trees. Riparian habitat and large trees will be avoided to the maximum extent practicable and trimming will be limited to trees directly within the road rights-of-way. c.

The project would not result in a substantial adverse effect on wetlands because directional boring techniques will be used to avoid impacts to sensitive resources. The US Army Corps of Engineers provided pre-project guidance stating there would be no impact to wetlands if all water crossings and wetlands are directional bored. If needed due to engineering or other constraints, trenching across some non-sensitive drainages would alter the streambed. Mitigation measures include stabilizing exposed soils and streambanks immediately upon installation completion in compliance with Section 404 of the CWA and obtaining authorization from the Corps of Engineers. Exclusion zones will be delineated around vernal pools and no construction activities will be allowed within those zones. d. Interfere substantially with the movement of any


The project would result in short-term and temporary disturbance and would not interfere substantially with migratory wildlife or impede wildlife dispersal. The OP-AMP sites are less than 3,000 square feet in size and are not located within established wildlife corridors or nursery sites. e. Conflict with any local policies or ordinances


The project could result in trimming, damage or removal of heritage trees, which may conflict with local government ordinances. Mitigation measures include avoidance to the maximum extent practicable and/or working with local jurisdictions to minimize impacts to these resources. f. Conflict with the provisions of an adopted Habitat


The City of San Diego and San Diego County Multi-Species Conservation Plan subarea plan documents and associated implementing agreements and ordinances were reviewed to evaluate the potential for inconsistencies with the proposed project. The MCAS Miramar Integrated Natural Resources Management Plan was also reviewed for inconsistencies with the proposed project. The project would not conflict with existing HCPs or other conservation plans. V. CULTURAL RESOURCES – Would the project: a. Cause a substantial adverse change in the




Ground disturbing activities could inadvertently affect cultural resources and the completed literature review yielded both historic and/or prehistoric sites along the route, as well as the potential for sacred lands. Implementation of mitigation measures, such as avoidance procedures and construction monitoring will reduce impacts to less than significant levels. If needed, alternate OP-AMP stations will not be sited in proximity to potentially and known significant historic resources. c. Directly or indirectly destroy a unique


Ground disturbing activities could inadvertently affect paleontological resources and the completed literature review identified high sensitivity for paleontological resources along several of the routes. Paleontological monitors will be employed in high sensitivity areas to recover, analyze, process, catalog, curate, and document fossil remains. In the event of a significant fossil discovery, construction will cease and salvage operations implemented. d. Disturb any human remains, including those interred


During construction activities, it is possible that human remains might be encountered. Compliance with state laws will ensure that potential impacts to human remains are below less than significant levels. VI. GEOLOGY AND SOILS – Would the project: a.
